Stubborn and ardent clinging to one's opinion is the best proof of stupidity.
Bordeaux, France
I study myself more than any other subject. That is my metaphysics; that is my physics.
I do not speak the minds of others except to speak my own mind better.
I do not care so much what I am to others as I care what I am to myself.
If your mind is empty, it is always ready for anything, it is open to everything.
The most dangerous worldview is the worldview of those who have not viewed the world.
The greater the ignorance the greater the dogmatism.
